Application Of Holographic Interferometry To The Study Of Hearing Mechanism

Holographic interferometry was applied to medical investigation regarding the vibration analysis of several parts of the sound conducting apparatus of mankind and some experimental animals. Vibration patterns of the tympanic membrane, the auditory ossicles and the skull were demonstrated and the results were discussed. Merit of holographic interferometry as a new technique of vibration analysis was emphasized, and several points to be considered by its application to medical investigation were also discussed.
